Application filed October 28, 1825. Serial Io. 65,861.

This invention relates to biishings for 'me-.

tallic receptacles, and the main object of the invention. is to providea bushing of simple, inexpensive land practical construction,

which may be quickly attached to a metal barrel or other receptacle insuch manner that the-bushing will be held against rotation when screwinga bung into or out of the bushing. v

Another object of the invention isto provide a bushing of said characterwith provision for preventing leakage between the wall of the receptacleand the bushing.

For a full understanding of the inventionreference will be had to theaccompanying drawings illustrating same, and the novel features thereofwill be particularly pointed out in the appended claims.

In the different views of the drawing,

similar characters of reference are. used to designate correspondingparts.

Figure 1 is a sectional elevation, taken on line 11 of Fig. 2 of abushing applied to the end of a metallic receptacle in accordance withmy invention,

Fig. 2 is a plan view of Fig. 1,

Fig. 3 is a sectional elevationof a bushing constructed in accordancewith my invention, before the bushing is applied to the end of themetallic receptacle, and

Fig. 4 is a sectional elevation of the end of a metallic rece tacleconstructed in accordance with my invention for the application of thebushing.

. Referring to the drawings, 1 represents the end ot a sheet metalbarrel or other receptacle, which is provided with an openin 2 formed bypressing therefrom an inward annular flange 3. A plurality of outwardlyextending projections or lugs 4 are stamped from the end of the barrel,and the inner rounding edge 5 of said lugs are substantially at a rightangle to the end of the bar-.

rel and the outer or u per sides 6 of said lugs are preferably inclined.The lugs 4 are arranged on the arcof a circle a -suflicient distancefrom the inner edge of the opening 2 to leave a seat 7 for a sealinggasket 8. A bushing 9 of cylindrical formation and having an outerdiameter corresponding to the inner diameter of anannular flan e 3 for 1fitting therein is provided with a ange 10 and threaded internally at 11for a bung. The outer edge of the flange 10 of the bushing is notched orrecessed at 12 for receiving the lugs 4 to hold the bushing againstrotation. Theother end of the bushing 9 is cut at 13 so as to leave atapering portion for bending over the edge'of the annular flan e 3 .asshown at 14. When the bushing 9 is assembled in the opening 2 of the endof the barrel, said bushing is securely held in osition against rotationwhen screwing a ung into or out of the bushing, and the gasket 8prevents leakage between the end of the barrel and the flange of thebushing.

From the drawings and description, it is obvious that a bushing formetallic receptacles thus constructed is simple and inexpensive tomanufacture and assemble, will be securely held in position againstrotation,

and there will be no leakage between the wall oft-he receptacle andthebushing.

Having fully described my invention 'what I claim is:

1. The combination with the wall of a metallic receptacle of a bushing,the wall having an opening formed therein, a flange forming a seatsurrounding the opening, lugs extending from the wall beyond said seat,the bushing having an annularflan at one end adapted to engage saidseat, t5: flange of the bushing having notches cut in its edge forreceiving and being engaged by said lugs, and the other end of thebushing being bent over the inner end of said annular flange of thebushing for clamping the bushing in position, substantiallv asdescribed.

2. The combination withthe wall of a metallic receptacle of a bushing,the wall having an opening formed therein, an annular flange forming aseat surroundin said opening, lugs formed integrally in said wall andextending beyond said seat, the bushing having a circular flange at itsouter end, the circular flange of the bushing having notches cut in itsouter edge adapted to fit over and be engaged by said lugs, a gasketarranged within said lugs and between said seat of said wall and saidflange of said bushing, and the other end of the bushing being bent overthe inner end of said annular flange for clamping the bushing intoposition, substantially as described. A

In testimony. whereof I affix my signature.
